Phase I/II Study of 9-ING-41, a Glycogen Synthase Kinase-3 Beta (GSK-3β) Inhibitor, as a Single Agent and Combined With Chemotherapy, in Patients With Refractory Hematologic Malignancies or Solid Tumors
Considering participating in a START clinical trial?
Study Summary
To evaluate the safety and efficacy of 9-ING-41, a potent GSK-3ß inhibitor, as a single agent and in combination with cytotoxic agents, in patients with refractory cancers.
The 1801 study will have three parts:
Part 1 (9-ING-41 as monotherapy): The standard 3+3 dose escalation design will be applied to all dose cohorts until the Maximum Tolerated Dose (MTD) or Recommended Phase 2 Dose (RP2D) is identified
Part 2: 9-ING-41 combined with standard anticancer agents: The 3+3 dose escalation study design will be used for 6 chemotherapy combination regimens (9-ING-41 plus gemcitabine, doxorubicin, lomustine, carboplatin, nab-paclitaxel plus gemcitabine, paclitaxel plus carboplatin) to identify the MTD/RP2D of each regimen. Part 2 will be started after a maximum of 3 dose escalations of 9-ING-41 as a single agent in Part 1. The starting dose level in Part 2 of 9-ING-41 within the six combination regimens will be the 3rd dose level of single agent 9-ING-41 (or lower if the IDMC so recommends). Dose escalations of 9-ING-41 as a single agent in Part 1 will continue in parallel with dose escalations of 9-ING-41 in combination treatments in Part 2.
Part 3: Assessment of activity of 9-ING-41 based combination regimens: The primary objective for Study Part 3 is to assess the clinical benefit of each of the six 9-ING-41-based combination regimens.
To evaluate the safety and efficacy of 9-ING-41 as a single agent and in combination with cytotoxic agents, in patients with refractory cancers.
To evaluate safety and efficacy of 9-ING-41 as monotherapy and combination therapy in pts with refractory cancers.
Part 1 and 2:
Evaluate the safety, describe dose-limiting toxicities (DLTs), determine the maximum tolerated dose and the recommended phase 2 study dose (RP2D) for 9-ING-41 as monotherapy (Part 1) and as combination therapy (Part 2).
Part 3:
(Simon 2-Stage Phase 2) assess clinical benefit in pts treated with 9-ING-41-based combinations at the RP2D established in Part 2.
To evaluate the safety of 9-1NG-41 as monotherapy (Part 1) and in combination chemotherapies (Part 2) in patients with advanced malignancies using standard 3+3 escalation design
To determine the maximum tolerated dose (MTD) or the recommended Phase 2 study (RP2D)
Genomic sequencing reports were reviewed for somatic alterations deemed potentially actionable or biologically relevant. For those with PDAC, best response was determined using RECIST 1.1 for those who completed at least two cycles of treatment. Chi-square frequency statistics were used to show the observed versus expected rate of pathogenic variants between patients with disease control (complete response [CR], partial response [PR] or stable disease [SD]) and progressive disease (PD).
To evaluate the efficacy and safety of elraglusib in combination with GnP in advanced PDAC.
Pre-dose peripheral blood protein levels were examined as binary predictors of clinical outcome using optimal cutoff points determined by maximally selected rank statistics. In the aggregate Part 1 and 2 populations (n=45), we identified 13 CCSG that significantly stratified the cohort by overall survival (OS).
To compare the combination of elraglusib with gemcitabine/nab-paclitaxel (GnP) to GnP alone as a first line therapy in patients with metastatic pancreatic cancer (mPDAC).
To determine the 1-year survival rate of patients treated on the 9-ING-41 schedule chosen from the run-in stage of the study compared to the control arm.
Cytokine/chemokine correlative biomarker assays were performed.
